The MILWAUKEE M18 FUEL 1/2 in. Mid-Torque Impact Wrench w/ Friction Ring delivers the best power to weight ratio, most access in tight spaces, and faster removal speed. It provides 650 ft. lbs. of nut-busting torque and only weighs 5.1 lbs., making it extremely versatile, capable of performing a wide variety of applications. Its POWERSTATE Brushless Motor generates the power needed to quickly perform many tasks, such as removing large bolts or lug nuts. This cordless impact wrench is the most compact in its class, giving users access to stubborn fasteners in spaces where larger impact wrenches can't fit without needing to disassemble components to reach bolts. Tri-LEDs surround the anvil to deliver brighter light with fewer shadows. 4-Mode DRIVE CONTROL offers greater precision with a range of pre-set RPM and IPM levels, selectable from a single button on the tool. By selecting Mode 4, AUTO SHUT-OFF control applies no more than 35 ft. lbs. of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Control that delivers users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops.The Milwaukee M18 REDLITHIUM XC5.0 Starter Kit delivers up to 2.5X more runtime, 20% more power and 2X more recharges than standard lithium-ion batteries. The lithium-ion battery pack features superior pack construction, electronics, and performance providing users more work per charge and more work over pack life than any battery on the market. The rechargeable battery also delivers users with 5.0 Amp-hours of runtime. Each battery pack is durably built for heavy-duty use, runs cooler, and performs in climates below 0 degree F/minus 18 degree C. This protection routes water away from the electronics and out of the battery pack, extends the users' battery run-time and life by minimizing heat, and prevents pack failures from vibration or drops.
